Located in Lawrence County, Pennsylvania, McConnells Mill State Park covers over 2,500 acres of forested land carved by the Slippery Rock Creek. The park is known for its impressive sandstone gorge, which cuts through the landscape, exposing rock formations and creating opportunities for hiking, rock climbing, and trout fishing.

Popular recreational activities include hiking along more than 14 miles of trails, exploring the scenic covered bridges, rock climbing on steep sandstone cliffs, and kayaking or fishing in the creek's wild waters. With its combination of natural and cultural features, McConnells Mill State Park draws visitors interested in outdoor sports, nature observation, and regional history.
